tofore been generally manufactured of canvas which is a fabric woven from cotton and in some instances has been made up from fabric woven from wool Such fabrics after being'suitably water-proofed to render them air tight are cut into long strips which have their longitudinal edges stitched together to form a hose section. Grommets are usually mounted in the side seam for the reception of the suspension wire, cable or the like which is usually employed for suspending the hose in the mine workings where it will be out of the way and least liable to injury.

Obviously hose for the purposes in question is used under conditions which expose it constantly tomoisture, and experience has shown that the fabrics heretofore used in the manufacture of the hose will be attacked with mildew, fungus, or like disease resulting from long subjection to moisture, or acsid o serious is this problem that. undernormal conditions of the mine usage piping though well water-proofed will not in many instances last more than six weeks. I I have further observed, after long practical experience with air hose of the character in question, that the strain of. suspen sion of the pipe either horizontally or yerti cally results very shortly in a tearing or breaking of the seam when the pipe is handled and this is particularly .true in the case of hose suspended vertically where the up? per sections mustcarry the load of the lower sections which hang therefrom.

*The object of my resent invention is to provide an air hose 0 the character in question which shall possess the maximum durability and strength without being materially increased in cost, and such object is attained; first, by weaving the fabric from which the hose is formed of animal hair which will be substantially proof against mildew or fungus attack under conditions .of moisture, the best hair. for this purpose which I have found being a mixture of camel ,and llama hair, which will, after treatment to render it moisture-proof, last indefinitely; andsecond, by taking care of the mainstresses and strains on the seam of Application tor 2 is a vertical cross-section on the line 22 of Fig/ 1.

Fig. 3 is a small sized view of a complete .hose section.

Similar reference numerals refer to similar arts throughout the drawings.

I illustrate a ose section 1 having suitable joint forming ends 2 which can beof any desired character and provided, intermediate 1 said joints, with a .Sideseam 3 having the .two seam members 6 and 7 and an extension edge 8 on the seam member 7 which is folded back down against: the rm ll ber 6 and bound to the. other two seam members by the stitching 4 and 5. I'place in the loop formed a jtthje outer ends of the members 7 and 8 a rope, cable or other reinforc ing andsuspension element 10 and throu h the seam members 6, and8 between t e seamss and-5 I pass grommets 11, the cable being anchored at both ends by being passed around the end grommets and bound in at its free end by stitching 12, or secured to the 1105.8 or its seam in any 'other suitable manner which will hold it firmly so that it will resist the stresses and suspension strains which may fall on the seam or hose from the suspension device conventionall indicated at 13 in Figs. 2 and? 'By t us incorporating the reinforcement in the seam oi-otherwise securing it to the hose lengthwise of the seam it is in position to reinforce the grommets, and to distributethe suspen- I The'fabric from which the hose is formed A is woven of animal hair, preferably camel hair or a mixture of camel and llama hair, which is subsequently water-proofed. I have discovered that fabric woven of such hair not only possesses great strength, which is already well known from the use of camel hair for belting and the like, but has the added property of being highly resistant to fungus attack -when subjected, for long periods to dampness, acid water, and moisture and this property is more valuable'for the purposes which I have in mind than the mere element of strength in the fabric itself. I

Though I have described with great particularity the details of the embodiment of the invention herein shown, it is not to be construed that I am limited thereto, as changes in arrangement and substitution of equivalents may be made by those skilled in the art without departing from the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. An air hose constructed of flexible fabric, sewn to form a longitudinal buttjoint, and having flexible joint-reinforcing means extending along said joint and secured to the hose, and suspension means cooperating with the butt joint and reinforcing means, whereby said reinforcing means receives the weight of the hose.

2. An air hose as claimed in claim 1, in

which said suspension means comprises a series of grommets placed in the butt-joint, between the reinforcing means and the outer periphery of the hose. 3. 'An air hose constructed of flexible fabric, having a butt-joint extending longitudinally thereof, and flexible reinforcing means sewn into said joint, and suspension means cooperating with the butt joint and reinforcing means whereby said reinforcing meanssustains the weight of the hose.

4. An air hose constructed of flexible fabric having a air of members forming a butt-joint exten ing longitudinally thereof with oneof the members ofsa-id joint carried outwardly beyond the other member, turned back upon itself to form a loop, and secured to said other member; and flexible reinforcing means engaged by said loop throughout.substantially its length, whereby the weight of the hose is distributed along said reinforcing member.

5. An air hose for ventilating mines and the like, formed of-flexiblefabric sewn at a longitudinal butt-joint into tubular form, and having a longitudinal flexible rein forcing element extending substantially the length of said joint and secured to the hose at its ends and grommets mounted near the ends of said joint, the free ends of the min forcing element being passed around said end grommets and secured against displacement.

6. An air hose constructed of flexible fabric sewn longitudinally to provide a oint,

a flexible reinforcing means extending along and secured to' sald joint, and suspension means co-acting with the joint andv its reinforcing means whereby the weight of the hose is transmitted to and distributed along said reinforcing means.

7 An air hose constructed of flexible fabric having a longitudinal seam, in combination with flexible reinforcing means extending along said seam and secured to the hose, and suspension means adapted to coact with the seam between the hose and its reinforcing means to transmit to and distribute along the latter the strain of sup porting the weight of the hose.

8. An air hose constructed of flexible fabric sewn to provide a longitudinal outstanding loop, and flexible reinforcing means extending longitudinally of and incorporated in said loop, in combination with a plurality of suspension means cooperating at intervals with the loo and its reinforcing means whereby the weight of the hose is transmitted to and distributed along the said reinforcing means.

9. The combination with a flexible fabric hose adapted for suspension, of a reinforcing member extending longitudinally along and secured throughout its length to the hose, and a plurality of suspension elements disposed between the hose and the member for transmitting and distributing the weight of thehose to said member.

10. In a flexible fabric hose adapted for suspension, means providing an outwardly extending seam, a flexible-reinforcing member incorporated in the seam, and suspension elements co-acting with the seam to transmit to and distribute along the reinforcing member, the weight of the hose when suspended.

'11. In a flexible fabric hose adapted for suspension, a longitudinal joint, a flexible reinforcing member incorporated in the joint, and suspension elements coacting with the reinforcing member between said member and the hose, for-transmitting and distributing the weight of the hose to the reinforcing member when the hose is suspended.

12. In a flexible fabric hose adapted for suspension, a longitudinal joint formed by sewing the edges of the material together to provide an outwardly extending loop, a flexible reinforcing member sewed into the loop substantially the entire length of the hose, and a series of grommets provided in the material bet-ween the reinforcing member and the hose and so positioned as to transmit and distribute the weight of the hose to the reinforcing member when suspended.

In testimony whereof I affix my signature.

WILLIAM HOOPER EVANS.
